<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling a switch mode power supply having only one induction element and a plurality of outputs. <P>SOLUTION: In the control method of a switch mode power supply provided with a controllable period switching cell (SC) and having only one induction element (L) and a plurality of outputs, a total power level corresponding to the sum of individual power levels required by all outputs (OUTi), respectively, during each conduction cycle is thrown into the induction element (L), outputs requiring non-zero individual power levels are selected continuously for all cycles in the same specified order, and corresponding individual power levels are generated for respective outputs thus selected. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
